Came home today and found that i have no video coming from my monitor. The light comes on on it but no video. Popped open the case and my video card fan isnt spinning so not sure if thats the problem. Have a GeForce4 Ti card if that helps. Anyone else ever have this problem or heard of it? Want to post on here before having to shell out the dough for a new card since they are running about $200 right now and its about a 6 year old mac. Any help or suggestions would be great.
